Most people experience it as a familiar presence in the sky. Fewer realize how deeply it shapes the conditions that make the modern…

It begins life as the world’s most useful assistant — embedded in coding platforms, financial trading systems, logistics software, scientific research tools, and content creation engines. Companies and governments adopt it because it makes…
